' Application filed March l0, 1899. Serial No. 708,473. (No model.)

To all whom, it may concern:

Beit known that I, EDWARD H. GIESY, a citizen of the United States, and a resident of the town of Wyoming, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

The several features of my invention and the various advantages resulting from their use, conjointly or otherwise, will be apparent from the following description and claims.`

Among the features of my invention one of the most important is that which relates to a general arrangement of anice-box at one side in combination with a compartment or compartments covered with a vitrified lining, substantially as hereinafter set forth.

In the accompanying drawings, making a part of this application, and in which similar letters of reference indicate corresponding parts, Figure 1 is a vertical central section of a refrigerator, illustrating my invention, the section being taken in the plane of the dotted line 1 1V of Fig. 2, that face of the section being shown which faces toward the door. Fig. 2 is a vertical transverse section of the refr-ig# erator, taken in the plane of the dotted line 2 2 of Fig. 1, that face of the section being shown which faces toward the left in Fig. l. Fig. 3 is afragmentarysection taken through the lower part of the ice-chamber, the section being taken in the plane of the dotted line 3 3 of Fig. 1, that face of the section being shown which faces toward the rightin said Fig. 1. Fig. 4 is a top view of one of the crooks. Figs. 5 and 6 illustrate the form of crock when one crock occupies the entire division D. Fig. 5 is a vertical section of the said crock, that face of the section being seen which would face toward the left in Fig. 4. Fig. 6 is a vertical section of the same, taken in the plane of the dotted line 6 6 of Fig. 5.

A indicates the casing or outer shell of the refrigerator. The sides, front, and rear may be paneled or smooth or otherwise formed in an ornamental manner, as desired. Thel sides, front, and back are preferably insulated-that is to say, they contain a layer or stratum of a suitable nonconductor of heat. Thus in the illustrative case before us a space W is present between theouter casing and inner casing of the outward frame or shell of the refrigerator, and this space is filled with a substance which will not readily conduct heat. In the present instance these spaces Ware packed with mineral wool.y

The'refrigerator is divided vertically into twol main divisions by means of a central partition B. vOne of these divisions C is the ice` compartment, whose novel formation will be shortly described, and the other division D consists of one or more .compartments E. The ice-compartment is everywheresurronnded with a suitable lining Z, preferably a metallic one of zinc or thelike. The upper portion of this compartment has vertical sides. Lower down it has at front a ledge or shoulder (i3 and at rear a ledge or shoulder O3, and from this point the linings Z, leaving the sides of the refrigerator, approach one another as they descend, forming the front and rear inclined walls C4 C4. Another wall C5 on that side of the compartment C opposite to compartment E also inclines away from the adjacent wall of the refrigerator and downward toward the compartment E. Thus these three walls C4, C4, and O5 incliningdownward toward one another at last reach a common bottom or platform C6, of small dimensions, in which the open upper end of the drip-pipe O7 is located. Thus all liquid resulting from the melting of the ice is carried downward and brought into the dri p-pipe at a point near to compartment E. Just above or not far above this floor O6 the Wall of partition B of the refrigerator is provided .with an opening B2, preferably circular, through which the cold air from the ice-compartment is permitted to enter the lower portion of the division D.

In order to protect the edges of partition B at opening B2 and to prevent any moisture or liquid flowing down that surface of partition B which is in compartment O, I provide an annular Hanged guard B3 and locate the same at the edge of the opening B2, the guard projecting into the compartment O, substantiall y as shown. Any moisture or liquid llowing down the partition B on the side of compartment C and which would otherwise run into the opening B2 is caught by the lguard- .Nn ,r VVA fiange B3 and carried around the edge or side opening and delivered into the bottom C below, substantially as shown. It will thus be observed that the cold water in ice-compartment C is all of it approximated to opening B2 and assists in keeping cool the air which passes down through the ice-compartment. The ice is duly upheld and in the present illustrative instance by a simple construction heretofore indicated-viz., by the ledges or supporting-surface C3. These support the cross-bar ends R2 of the rack R, the longitudinal pieces R3 of the rack extending in parallel lines from one cross-bar R2 to the other and duly fixed to each. of the same. The ice rests upon such a rack as this. Provision is made for the admission of ice into the icecompartment, and in the present illustrative instance the ice is admitted through opening P, closed by means of a door Q, and this door is preferably provided with an insulated interior cover Q2. The door is hinged at Q3, and the opposite free edge of the door duly rests upon the top portion of the adjacent walls of the refrigerator. Admission to compartment D is duly provided. In the present instance there is a single opening in the refrigeratorin front of the compartment D, and this opening is closed by the door F, duly hinged. The construction of this door as regards its being provided with wallst'. e., non-conducting material-is similar to the construction of the rear side of the refrigerator. Provision is made whereby the cold air coming from the ice-compartment C in the compartment D can pass upward in front of the space occupied by the compartment D and also within the said compartment D near the rear thereof. This compartment is lined with porcelain or vitrified material, substantially as shown, the front of the porcelain compartment or compartments being open while the back thereof is entirely closed. That portion of the cool air which does not iiow up between the door and this porcelain compartment or compartments iiows up on the inside of the said compartments near the rear and in front of the latter.

The preferred construction of the refrigerator is duly illustrated in Figs. l and 2, in which case the compartment D is divided into two subcompartments E E, and each of these is composed of or lined by a crock or casing formed of vitrified material, open at front, closed at rear, and provided with sides, top, and bottom. The lower crock is provided at one side with an opening B2, and there is an opening E2 in its roof or top near its back side. The upper crock or compartment E is provided with an opening E3 in its bottom, located near its back side, and this opening E3 alines with the opening E2 in the roof of the lower crock. The two crooks may be set one upon the other, but preferably are separated by partitions or cleats A2, and in the event of this shelving A2 being present the latter is provided with an opening which coincides with the openings E2 and E3, so that the partition presents no obstacle to the air passing up through the openings E2 E3 from the lower crock into the upper crock E. The upper crock E is also provided in its roof with an opening E3 near its back side, and what air does not pass up between the front side of the refrigerator and the front edge or top of this crock will pass up through this upper opening E3 and into the passage-way G above the upper crock E, and thence over the top of partition B-viz., through the opening H into the upper portion of the ice-chamber C. Thusacurrent ofairis continually maintained within the refrigerator as follows: The air being cooled by the ice in compartment G passes downwardly'around the ice and between the bars of the rack R into the chamber C L, constituting the lower portion of chamber C, and thereby having become intensely cold passes through opening B2 into the lower portion of compartment D-viz., into the lower crock E-and fills said compartment,and there takes up heat from the articles of provision placed therein and passes up, and as it becomes heated some of it passing up between the door and the front adjacent edges of the crooks E E, and therest of this air passing up through openings E2 E3 of these crooks into the upper crock E and there withdrawing heat from the provisions therein again divides and part of it passes up behind the front of the refrigerator and in front of the roof of the upper crock and the other part passes up through the upper opening E3 of the upper crock, and all of this heated air passes into and through chamber G through opening H into ice-compartment C. Here this air is again cooled and at the same time deposits upon the ice the infinitesimal particles of odor and the like, which are taken up from the food in the upper and lower crooks E E of compartment D. Where the compartment is what may be termed one compartment L E-ethat is to say, where there is only one porcelain crock and that takes the place of the two crooks E E--this vitrifled crock is provided with an opening B2, located near its lower end, so as to register with the opening B2 through partition B, as hereinbefore indicated and in the same manner as the opening in the lower crock E [its the opening in partition B, and there is in the roof of this crock L E an opening E3, located near its back side and substantially similar to that shown in the upper crock E of Fig. 2. Where one large crock L E is present, it will be provided with suitablelugs or projections S on its inner sides for the sustaining of racks crossing from one projection to the other, lying in the same horizontal plane. The preferred shape of these lugs in cross-section is that of a bead, as that term is used in the parlance of carpenter work. I have locatedA one of these sets of projections S, usually the lower ones, so that their plane, if extended, would pass through the center or near the center of the opening IOC' IIO

B2. Thus the rack located upon these lastnamed projections will be in such a'position that the cold air coming in from the ice-coinpartment C will part of it-go below said rack and part of it go above the said rack. The openings E2 and E3 are substantially as shown in Fig. 2. The opening inthe bottom may be one long continuous slit or be divided by a crosspiece or neck T, preferably employed in the case of large crooks to'strengthen them. The upper crock E is also provided with a ledge or projection E4, located immediately in front of the opening E3, and in order to make the upper crock reversible there is a similar projection provided on the lower side of the root' of the crock and immediately in front of the opening E3. .The f nnction of this projection is to prevent the food or provisions placed upon the bottom of the crock from being pushed too far back, and thus stopping the opening EB in the rear ot' the crock or falling down through the same. The ledge also is of benefit in preventing any liquid spilled upon the floor of the upper crock from dripping down through opening E3 into the crock below. Where the partition A2 is present between the door and the lower crooks, the front edge of it is preferablyprovided with a cleat A3, which extends up and down in front of the front edges of the adjacent portions of the upper and lower crocks and forms a finish.

Among the various obvious advantages resulting from theuse of my invention and its several features is the following one,viz: The arrangement makes a very cold refrigerator because the ice is located very near the opening from the ice-compartmentinto the foodcompartment. The ice rests j ust above or near to where the cold air is carried into the food or preserving chamber,and the ice-chamber itself is alongside of and on a level with the upper part of the provision-division D, so that there is no excessive distance to be traversed by the air-current, which merely moves laterally across the top of partition B and in an opposite direction through opening B2 in its circulation between the divisions C and D. The tops of the crocks also serve to afford a better circulation through the provision-compartments of the rising air from opening B2 by causing said air to divide so that one portion iiows up next to the door F, while another portion of such air passes up through the openings E2 EB in the back parts of the crocks. In their function of thus assisting in circulating the air through the provisiondivisions the tops of the crocks or linings constitute horizontal partitions extended across the provision-division and provided with openings near their front and back edges, through Wnich the air may pass upward; As the air circulates around the ice the odors, which'are minute particles and are given olf by the food, are deposited on the ice, so that at the time the air first travels around the ice and travels back into the foodcompartments it is entirely freed from the odors it contains.

Hence foodof a delicate nature, such as butter and milk, vdeposited in the lower part of the compartment is not tainted Aby food of strong odors kept above in the compartment.

I have hereinbefore employed the words vitriiied and porcelain in connection with the material of which the crocks are composed and desire it to be understood that the material of which the crooks are made may be stoneware or any other vitritledsubstance or material covered with a vitrilied glaze or glaze formed on the article by heat and that such classes of material are to be understood as constituting the substances out of which the crccks or linings of the provision-compartments are made.
